Problems solved by technology

Unsaturated fatty acid soap is easy to oxidize and deteriorate, and has poor resistance to hard water. When the cutting fluid is used for a period of time, the emulsion will break and deteriorate due to the increase of aluminum ions; and organic compounds such as sulfur and phosphorus mixed in water are nutrients for microbial reproduction. Agents will accelerate the reproduction of bacteria and molds in the emulsion, causing the emulsion to stink and deteriorate
As a result, the lubrication and cooling performance of the cutting fluid is reduced, the processing cannot meet the product requirements, the tool life is short, the cutting fluid replacement cycle is short, the waste liquid discharge is large, and the production efficiency is reduced.

Description

technical field [0001] The invention relates to the field of cutting fluid for mechanical processing, in particular to a synthetic ester environment-friendly aluminum alloy cutting emulsified oil and a preparation method thereof. Background technique [0002] Since the 1980s in my country, a large number of aluminum alloy materials have been used in the real estate construction industry, automobile manufacturing industry, aerospace industry, telecommunications and electronic engineering, and the high-speed rail manufacturing industry that has developed rapidly in recent years, making aluminum alloy processing very universal. Compared with most ferrous metals, aluminum alloy has low hardness and requires less cutting force during processing, but the flexibility of aluminum alloy is prone to bonding during cutting, forming built-up edge on the cutting edge, which increases cutting resistance , Seriously affect the surface roughness and precision of the workpiece. At the same ...
